Big lag in big files

[gerazov]

Describe the bug

I'm having lag issues when editing big org files in insert mode. The lag doesn't happen when navigating the file or folding/unfolding.

The problem is not decreased after turning off syntax highlighting by running lua vim.treesitter.stop()

It seems that complex file structure aggravates the issue. In my org files it is already really laggy at 2000 lines. To replicate with a test file I had to go up to 8000 lines. Here's the file with an md extension:

test1.md

The problem also appears when using the minimal_init.lua. The problem doesn't appear when editing the same file as md and not org via the minimal init.
